Improvement in plows



i LEVIS B. \VHITE, OF NORFOLK, VIRGINIA, ASSIGNOR TO HIMSELF AND S. It.WHITE, OF SAME PLACE.

IMPROVEMENT IN PLOWS.

Specificaion forming part of Leiters Patent No. 164,952, dated June 29,1875; application tiled Y May s, 1875;

To all whom it `may concern:

Be it known that I, LEwIs B. WHITE, of Norfolk, in the county of Norfolkand State of Virginia, have invented certain new and useful Improvementsin Flows; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable Others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a .part of this specification.

The nature of my invention consists in certain improvements upon theplow for which Letters Patent N o. 140,749 were granted tome July 8,1873, as will be hereinafter more f'ully set forth.

In the annexed drawing, Figure l is a side elevation of' my improvedplow.' Fig. 2 is a plan view of the same. Figs. 3, 4, 5, 6, and 7 aredetached views of certain parts thereof.

A represents the plow-beam, to which the frame B is secured by a bolt,a, passing up through the t'op of' the frame and through the plow-beam.The -opening b in the frame is curved forward at its upper endflfor thepurpose of' throwing the bolt a farther forward, and thus decrease theleverage from the front end of the beam, and th'ereby lessen theliability of breaking the bolt. The side of the frame is formed with ahorizontal shoulder, e, at a suitable height above the lower edge, andalong said lower edge is formed an inwardlyprojecting inclined andtapering flange, d, which is made slightly concave on its under surface.At the point of the frame B is formed a shoulder or abutment, f. Theinside of the frame B is formed with flanges b around the opening b, andalso with two parallel anges, a a', and with a ange, d', as shown inFig.

7, to obtain the greatest amount Ofstrength.

O represents the landside, which is made pointed at both ends, andprovided on each side with a tapering iiange, h, which com- Inence fromopposite ends and gradually run into the body of the land-side, saidflanges being convex on their upper surfaces to lit against the concaveflanged of' the frame. When the land-side O is fastened to the frame itsupper edge .is against and flush with the l the flange d of the frame.

shoulder e, its point against the abutment f, and the iiange It on itsinner side up against As the outer side of' the land-side becomes toomuch worn it can be reversed and put back in place, and

one end of' the iiange on the lower part of the land-side is thickerthanthe other, so that when worn it is reversed. D represents the plowshare or point, and E the mold-board. rlhese are both at their inneredges constructed with a flange, t', to form a V-shaped groove,

which nts over the edge of the frame, and the dan ge of the mold-boardat its upper end interlocking with a shoulder, 7c, on the-frame. Whenthe share and mold-board are fastened in place they form one continuouscurve from the point to the shoulder Ic, and at this shoulder on theframe is formed, so to say, an elbow, the upper end of the frame forminganother curve. On the wing of the frame B is formed a rib, m, whichcomes directly at the junction of the share and mold-board, and fits yinrecesses n, made 'in their edges for that purpose. This rib acts as aguide in putting ou the share and mold-board, and in drilling or reamingthe bolt-holes therein. It also acts as av stop for the share andmold-board, so as to relieve the bolts which fasten the same from unduestrain, and to prevent the twisting of' either share or mold-board. Thisis of great importance, from the fact that both the share and mold-boardare each fastened only by a single bolt.

It will be seen that in operation the flanges t' of the share andmold-board protect the edge of' the frame, and, as they projectl beyondthe edge, they also protect the side of the frame.

P P represent the handles, the lower ends of which are laid between theiianges a a and fastened by bolts c e', the iianges holding the handlesfirmly in position and relieving the strain on the bolts. Between theframe and the handles is inserted a slotted wedge, B, to pass over theupper bolt, e', and the outer side of this wedge is toothed, as shown inFig. l. Between the upper rear ends of the lianges a a. is formed anedge, i', which engages with the toothed wedge B, to hold the same andprevent its slipping. The object of this wedge is to adjust the handles,as required, more or ATEET GEEIcE.

less to either side. Between the handles P l?, in rear of the beam A, isfastened a slotted and flanged casting, S, formed with a projec.

tion, f', on its front edge. This projection is recessed on its upperside, and provided with an elongated slot. On the under side, at therear end of the beam A, is a block, 7L', let into the beam, which blocklits into the recess in the projection f said projection resting againstthe under side of the beam, as shown in Fig. 3. A bolt, c, is thenpassed through (from underneath) the slotted projection, block, andbeam, and fastened by a nut on top. The rear portion of the casting Sforms a flanged extension between the handles, having a slot, s', in thelower part, to allow the casting to move over the bolt s. The upperportion is also slotted and provided with angular openings correspondingin form to the shape of the bolt-head, by which means the casting isadjusted and held in place. The casting is also provided with ribs t',which holds one of the handles n proper position.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The tapering concave flange d, formed on the lower edge of the frameB, in combination with the reversible double-pointed landside C,provided with tapering flanges h, made thicker on one end than on theother, substantially as and for the purpose specified.

2. The frame B, provided with flanges a! a and edge in combination withthe slotted and corrugated wedge B and handles P, all as and for thepurpose herein specied.

3. The casting S, having recessed and slotted projection f', flanges orribs t t', slot s, and slot for bolts t, in combination with handles P,beam A, and block h, all as and for the purpose set forth. j

In testimony that I claim the foregoing as my own I at'iix my signaturein presence of "two witnesses.
